1. A coil component comprising:
a core including a winding core portion and a pair of flange portions, configured such that one of the flange portions is provided on one end of the winding core portion and an other of the flange portions is provided on an other end of the winding core portion;
electrode portions provided in the pair of flange portions, respectively;
a wire wound around the winding core portion, both ends of the wire being electrically connected to the electrode portions; and
a magnetic plate fixed to the pair of flange portions so as to straddle the pair of flange portions, wherein
the magnetic plate includes
an annular first planar portion,
a second planar portion that is located inside an inner circumference of the first planar portion as seen in a direction orthogonal to the first planar portion and has a step between the first planar portion and the second planar portion, and
a connection surface portion that connects the inner circumference of the first planar portion and an outer circumference of the second planar portion to each other,
the connection surface portion is configured by annularly disposing at least three slopes inclined with respect to the direction orthogonal to the first planar portion, and the connection surface portion has chamfered portions each being disposed between adjacent slopes of the at least three slopes; and
an adhesive between the at least one flange portion and the magnetic plate to bond the magnetic plate to the at least one flange portion such that the magnetic plate and the at least one flange portion are out of direct contact with each other.
